The invention provides induction welding equipment and method for a thermoplastic resin matrix composite with an internal electromagnetic material, belongs to the field of material forming and manufacturing and solves the problems about induction welding materials and equipment. Innovations are as follows: in terms of the material, a lamination forming process is adopted for producing the thermoplastic resin matrix composite, an iron-based ferromagnetic material is added in a lamination process, and a composite welding piece is formed; in terms of the welding equipment, the induction welding equipment is improved, axial application of pressure is realized, the distance with a joint is controlled as required, and efficient induction welding is realized. The welding method comprises the steps as follows: firstly, pre-pressure is applied to a to-be-welded composite by pressurizing equipment, then an induction coil is connected, and an electromagnetic field is produced to heat the internalelectromagnetic material. The induction welding equipment and method have the advantages that the requirement of induction welding for size of a to-be-welded object is reduced, welding quality and efficiency are improved, energy consumption is reduced, the welding equipment is simplified, and one-time investment of the equipment and production cost are reduced.
